Another possibility is that they could be part of a group of friends in fanfiction. They might all work together to protect some magical habitats. Hermione's strategic thinking and Charlie's knowledge of the natural habitats of magical creatures would be a great combination. They could face challenges like poachers or dark wizards who want to use the power of the magical creatures for evil purposes.
In fanfiction, Hermione and Charlie could have a very adventurous relationship. They might team up to study some rare magical creatures. Since Charlie has a passion for dragons and Hermione loves knowledge, they could go on expeditions together. Charlie could introduce Hermione to the world of dragon keeping, and Hermione could use her intelligence to help Charlie with research on dragon behavior.
The plot might involve Hermione going on an exchange program to study magical creatures in a different country where Charlie is based. They meet and Charlie shows Hermione around the dragon habitats. As they spend time together, they discover they have a shared love for protecting magical creatures and a mutual respect for each other's knowledge. Eventually, they become friends and help each other out in various ways, like Hermione helping Charlie with some paperwork using her organizational skills.
In fanfiction, when Hermione flirts with Charlie Weasley, it might bring out a different side of Hermione. She's usually so studious and serious, but the flirtation could show her more playful and daring side. Charlie, on the other hand, might be a bit taken aback at first but then warm up to it. They could end up sharing their knowledge with each other, Hermione with her magic theory and Charlie with his dragon lore.
Perhaps in this fanfiction, Hermione discovers that Charlie has a hidden love for music. She decides to sing to him as a way to get closer to him. Their relationship might start as a friendship, but the act of singing could lead to deeper feelings developing between them over time.
Maybe Hermione gets involved in a situation where she needs to rescue a magical creature, like a baby dragon that has been captured by poachers. Charlie, being an expert in dealing with dragons, comes to her aid. They embark on a dangerous journey to find the poachers' hideout. Along the way, Charlie teaches Hermione some survival skills in the wild, as well as how to communicate with dragons on a basic level. In the end, they rescue the baby dragon and Hermione has a newfound respect for Charlie's skills.
One possible plot could be that Hermione gets injured during a dangerous magical experiment. Charlie, with his extensive knowledge of magical creatures and their healing properties, uses a rare potion made from a dragon's scale, which he obtained during his dragon - handling days in Romania. He combines it with some traditional healing spells to slowly heal Hermione's wounds.
One possible plot could be that Charlie comes back to Hogwarts for some reason, maybe to help with a dragon - related problem. Hermione, being the brilliant witch she is, is also involved in the solution. As they work together, they start to develop feelings for each other and eventually share a kiss. Maybe it's a moment of celebration after they successfully solve the problem.
Well, a frequent theme is the combination of magic and knowledge. Hermione's vast knowledge of magic and Charlie's practical knowledge of magical creatures often come together. Also, there is the theme of cultural exchange within the wizarding world. Charlie, who has been away in Romania, and Hermione, who is deeply involved in the British wizarding community, share their different experiences and views in many stories.
At first, their relationship might start as a simple protector - protectee one. Charlie sees Hermione in danger and decides to help. But as time goes on, they start to respect each other's skills more. Hermione admires Charlie's courage and knowledge of magical creatures, and Charlie respects Hermione's intelligence and magical abilities.
Yes, there are quite a few. You can start by looking on fanfiction.net or Archive of Our Own. Just search for 'Charlie Weasley and Hermione' and you'll find a variety of stories, from adventure - based ones where they go on dragon - related quests together, to more character - study - like fictions that explore their relationship in the wizarding world.
I'm not sure if there is a specific fanfiction with that exact title. There are a vast number of Harry Potter fanfictions out there, and while some might involve Charlie Weasley and Hermione in some way, it's hard to say if one has that rather odd - and perhaps a bit concerning - description. It could be a very niche or even a made - up idea for a fanfic that may or may not exist.
